Refrigerating and freezing device

Abstract

A refrigerating and freezing device (1) is provided, which includes: a cabinet body, wherein at least one storage compartment (11) is defined in the cabinet body, and a heating cavity configured to accommodate a to-be-processed object is defined in one of the storage compartments (11); and an electromagnetic heating device, configured to provide electromagnetic waves into the heating cavity to heat the to-be-processed object, wherein the electromagnetic heating device is provided with an electromagnetic generation module (21) configured to generate an electromagnetic wave signal and a power supply module (24) configured to provide a power source to the electromagnetic generation module (21). An accommodation groove (12) with a backward opening is formed in a back of the cabinet body (10), the backward opening of the accommodation groove (12) is covered with a cover body (13) to define an accommodation space (14) between the accommodation groove (12) and the cover body (13), and heat dissipation holes configured to achieve communication between the accommodation space (14) and an external environment where the cabinet body (10) is located are formed in the cover body (13). The power supply module (24) is disposed in the accommodation space (14), and a heat dissipation fan (31) is further disposed in the accommodation space (14) and is configured to drive airflow to flow between the accommodation space (14) and the external environment where the cabinet body (10) is located through the heat dissipation holes, so as to dissipate heat from the power supply module (24), and the heat dissipation efficiency is improved.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of refrigeration and freezing, and in particular to a refrigerating and freezing device.BACKGROUND ART[0002]In the freezing process of food, the quality of the food is kept; however, the frozen food needs to be heated before being processed or eaten. In order to facilitate freezing and heating of food by a user, the prior art generally heats the food by providing a heating device or a microwave device in a refrigerating and freezing device such as a refrigerator. However, heating the food by the heating device generally needs a long heating time, and the heating time and temperature are not easy to control, which easily causes water evaporation and juice loss of the food, and the quality of the food is lost. Heating the food by the microwave device is fast and efficient, so the loss of nutrients in the food is very low. But the problems of non-uniform heating and local overheating easily occur due to the fact that the p...

AI Technical Summary

Benefits of technology

The present invention provides a refrigerating and freezing device with a large heating space and high space utilization rate. The device has an electromagnetic heating device that heats and thaws the to-be-processed object through electromagnetic waves, with high heating efficiency and uniform heating. The power supply module is located outside the cabinet body and does not occupy a storage space or a heating space, with a high space utilization rate. The device also has a heat dissipation fan and heat dissipation holes to quickly dissipate the heat generated by the power supply module to an external environment space, preventing the temperature rise and burn hazards caused by unintentional touch by users. The power supply module is covered with a cover body to prevent it from getting damp or attracting dust, ensuring the device operates safely and efficiently.

Problems solved by technology

However, heating the food by the heating device generally needs a long heating time, and the heating time and temperature are not easy to control, which easily causes water evaporation and juice loss of the food, and the quality of the food is lost.

But the problems of non-uniform heating and local overheating easily occur due to the fact that the penetration of microwaves to water and ice and the absorption of water and ice to microwaves are different, the distribution of internal substances of the food is not uniform, and much energy is absorbed by a thawed area.

However, the previous electromagnetic heating device will occupy too much heating space, and the heat generated by the electromagnetic heating device is not easy to dissipate, thereby affecting the heating effect.
